Examples of septic obstructive pulmonary diseases are:
• cystic fibrosis
From which type of obstructive disease are you more likely to get an infection?
Emphysema is caused by a destruction of the air spores. Describe the differences in how the alveoli appear:
normal alveoli are pink, and nicely rounded.
In emphysema the air spaces areas are stretched out and appear darker in appearance.
What is impacted in restrictive pulmonary disease?
In restrictive pulmonary disease its hard to get air ____________ and in obstructive pulmonary disease it is hard to get air _________.
Restrictive pulmonary disease is:
• linked to immune disorders, occupational exposures, genetic and hormonal abnormalities and a complication of lung injury
• loss of lung compliance and chest wall expansion
• decreased depth and increased rate of breathing
In restrictive pulmonary disease, the lung tissue is less _____________ and becomes ___________________
tighter and tougher

Normal FEV1/FVC ratio =
in obstructive disease, the ratio of FEV1/FCV :
FVC is stable and FEV1 is smaller
Asthma is an example of what type of pulmonary disease?

What is the most common childhood disease?
how many deaths/year are associated with asthma?
Ethnic difference in asthma prevalence, morbidity and mortality are highly correlated with:

wheezing is described as:
high pitched whistling sounds when breathing out
List some signs and symptoms of asthma:
